' a citizen of the United States, residing at fNbrthb'oro; in the county of Worcester and {State of Massachusetts, haveinvented a new 'yandiuseful Jack for Vehicles, of which] the b wi nai'isx pe i e nin "entijonrelat'es to a ackadapted to f b pp-h mt e el-pi a eh c pan l larlyan automobile; forl-liftingit by'its ow'n power and leavingi lifted ina 'fs'table lcondition"for"the"purpose of changingitir .theliker The principal objects of the inventmn'Eare llprovide'a simple and convenient'device fior theabove inentioned purposeada ted and to e Secured in position quickly and in a' very simple manner and'also to provide it insuch away that when the vehicle is inoved slightly inone direction the jack will come into 50 eration automatically and lift thfi wheel without any operation of the ac'k fromju'nder the vehicle. 7

Referenceis to be had to the accompanyin drawingsgin which-,

i 1 is a" side. view of an automobile whee showing itlifted by this jack;

Fig. 2 isa similar viewrshowing it in the op a i v- Fig, 8 is a front edge view showing 1ts relation to the wheel; and a Fig. 4 isa plan showing the wheel spokes in section. The invention is shown in a form involving .a block 10 of wood, pressed metal orcast metal of a generally triangular shape 7 and having aprogection 11 of similar shape adapted to be received between the spokes of a wheel. FIhis-pro'jection is'slightly les's in thickness thanthethickness of the spokes extends down to'provide a curved surface 16 adual curve below the tire 21 and having a 17 at each end to a point ad acent to the from lthe rear or inner side. of the wheel in {the posltion shown inFig. 2. The cross bar fi i ' adjacent spokes, the block being located betvvee'nlthem'l It is assumed that at this time can-ib'eiperforljned convenientl to bea gpliedbetween two spokes of aw eel positlon assumed before or after the lifting faces 16 and 17 (constitute the bottom of the block and the surface 16 is preferablycurved on the center'of the wheel as a center.

60 Inrthc use of. the.devicethe crossbar 14 v {,is turned to a position at right anglesrto tliosefshown and the projection 11 entered through thejspacelbetiveen two spokes 22 14]is then turned to the position shown in' that figure to restton the outside of the two thefnut1'l3 is loose so that these operations Now, the nut is-tightenedioihold the ack in place onthe wheel and either-the engineis started to move the car forward or back on it can be pushed to bring the parts around to the position shown in'Fig. 1. p o It will be seen that the projecting surface 16'will extend far enough below the tire to lift the whole tire-andfwheel up so that the tire is relieved from pressure on the ground and is held elevated. It is to be noted that the wheel cannot be turned in this position and the tire and rim can be removed more readily on thataccount because the wheel is fixed in position and there is no danger of the operator injuring his knuckles on account of accidental turning of the wheel as is the case with the use of ordinary jacks.

When the jack is in the position shown in Fig. 1, thatside of the caris held up by it. It has two sets of surfaces which erform this function. The converging sur aces of the triangular projectiitns 11 come between the spokes and support the wheel by the restingof the spokes tan-these "surfaces lThe surfaces 15 supp'ortthe wheel s It will be seen therefore that this jack provides the. above mentioned advantages in a most convenient and simple manner and that atire and rim canbechanged'in a very easy way without getting under the car or running any risk of the jack slipping out from under the axle ashas been the case Y heretofore.

' Although I-have illustrated and described only a single form ofthe invention, I am aware of the fact that modifications can be made therein by any erson skilled in the art without departing rom the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to allthe details of construction herein shown and described but What I do clann 1s- 1. As an article of manufacture, a jack adapted to be attached tothe side of a wheel,

comprising a block having a surface extending beyond the tire and provided with a"'1ateral projection of general triangular shape projecting through the space betweeirtwo spokes and adapted to fit against their sides substantmlly throughout their 1ength,and means extending from sald pro ection for fixing-the projection and block to the spokes of the Wheel. I 2.As, an artlcle of manufacture, a ack for the Wheel of a vehicle comprising a' substantially flat'trlangular bloclchav ng a surface pro ecting materially beyon'dthe tire of the Wheel provided with gradually curved ends having means for fining it to the spokes of thewheel, and having oppo' spoke.

site flat converging surfaces for engaging the spokes and having an endsurface adapt- "ed to engage the hub to supportthe wheel.

across bar adaptedto swing on said bolt and to engage the oppositeouter'side of said In testimony whereo f "I jhaye hereimto I affixed my signature.
